The Castile and León appellation, located in the northwest of Spain, is a renowned wine region that encompasses several sub-regions with distinct viticultural characters. This vast area is known for producing high-quality wines that blend tradition and innovation. Among the most famous estates, Ribera del Duero is celebrated for its powerful reds, primarily made from Tempranillo, often compared to great Bordeaux wines for their complexity and aging potential. Another notable sub-region, Rueda, is recognized for its lively and aromatic white wines made from the Verdejo grape, offering tropical fruit aromas and captivating freshness. Toro, known for its robust and concentrated reds, also focuses on Tempranillo, locally called Tinta de Toro. Thanks to a continental climate with hot summers and cold winters, combined with a variety of soils, the wines of Castile and León benefit from a diverse terroir. This region, rich in history and wine culture, continues to captivate both enthusiasts and connoisseurs, affirming its crucial role in the Spanish winemaking landscape.
